ELM 4-300 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-300 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.300" (7.62mm) vertical height. This component is designed for mounting 3mm LEDs in vertical orientation with 2-lead configuration. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when design requirements permit variation in standoff height, material composition, or series designation while maintaining compatibility with T1 LED form factors and 3mm LED mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-300 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• LED Size: 3MM (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• Orientation: Vertical (fixed requirement)
• Color: Black (fixed requirement)

Variable Parameters Permitting Substitution:

• Height: 0.285" (7.24mm), 0.300" (7.62mm), or 0.315" (8.00mm)
• Material: PVC or Nylon
• Series: ELM 2, ELM 4, or H101C

Substitute parts maintain all fixed parameters while allowing height variation within the specified range and material selection between PVC and Nylon compositions. All substitute parts retain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance equivalent to the ELM 4-300. Selection among substitute options is determined by application-specific height requirements and material preference.

Height-Based Selection:

• 0.285" (7.24mm): ELM 2-285, H-101C, H-101C-1
• 0.300" (7.62mm): ELM 4-300 (primary part)
• 0.315" (8.00mm): ELM 2-315, ELM 4-315

Material-Based Selection:

• PVC Material: ELM 4-300, ELM 2-285, ELM 2-315, ELM 4-315
• Nylon Material: H-101C, H-101C-1

All substitute parts carry MSL 1 rating and ROHS3 compliance, ensuring equivalent environmental and moisture protection characteristics.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-285 replace ELM 4-300 in all applications?

A: ELM 2-285 is a parametric equivalent with identical LED type, size, lead configuration, color, and material. The difference is height: 0.285" versus 0.300". Substitution is valid only when the 0.015" (0.38mm) height reduction does not affect circuit board layout or LED positioning requirements.

Q: What is the difference between PVC and Nylon standoff materials?

A: Both materials are provided in the substitute list. PVC variants include ELM 4-300, ELM 2-285, ELM 2-315, and ELM 4-315. Nylon variants include H-101C and H-101C-1. Material selection depends on application requirements for mechanical properties and environmental resistance.

Q: Are H-101C and H-101C-1 interchangeable?

A: H-101C and H-101C-1 share identical specifications: 0.285" height, Nylon material, T1 LED type, 3MM size, 2-lead configuration, and Black color. Both maintain ROHS3 compliance and MSL 1 rating. They are functionally equivalent.

Q: Does height variation affect LED mounting compatibility?

A: All substitute parts maintain T1 LED type and 3MM LED size specifications. Height variation (0.285", 0.300", or 0.315") affects vertical standoff distance only. Substitution is valid when circuit board design accommodates the specified height.

Q: Are all substitute parts ROHS3 compliant?

A: All parts listed—ELM 4-300, ELM 2-285, ELM 2-315, ELM 4-315, H-101C, and H-101C-1—maintain ROHS3 compliance and MSL 1 rating.

Q: What inventory levels are available for each substitute?

A: Current inventory: ELM 4-300 (997 Pcs), ELM 2-285 (1874 Pcs), ELM 2-315 (7562 Pcs), ELM 4-315 (4972 Pcs), H-101C (22132 Pcs), H-101C-1 (11998 Pcs).
